In biological system, the phospholipids often occur with other molecules are in bilayer such as cell membrane. Lipid bilayer occur when hydrophobic tail line up against one another, forming membrane of hydrophilic heads on both sides facing the water. A phospholipids is an amphipathic molecule which means it has both hydrophobic and hydrophilic components a single phospholipid molecules usually has a phosphate group at one end which is called as head and two side by side chains of fatty acid that make up the lipids tail.The hydrophilic heads of phospholipids in a membrane forms a bilayer that faces outwards, contacting the fluid both inside and outside of cell the hydrophobic usually known as water-fearing forms a part of a phospholipids which consist of long, non polar fatty acid tails.
The most important function of phospholipid is form phospholipid bilayer. In that bilayer this phospholipids are arranged such that all hydrophilic heads are pointing outwards and hydrophobic tails are pointing inwards.
In phosphodiestr bonds link successive nucleotides in nucleic acids these successive nucleotides of both DNA and RNA molecules are covalently linked through phosphate groups and hydrophilic forms a backbone of both DNA and RNA.
The hydroxyl group of sugar tends to form hydrogen bond with water . The hydrophilic phosphate heads like water so they get touched from inside and outside of cells and environment remains watery. Then the hydrophobic region in the middle which is free from water.Thus the cell membrane help in structuring the cell and also controls substance to cross.
The hydrophilic head pointed out and hydrophobic tail pointed in when the lipid is in water ,the phospholipid can be flexible and strong. This stable structure with fluidity allows the cell to change shape easily and maintain their structure too.
compare the hydrophobic and hydrophilic properties of phospholipids and nucleic acids. how does this relate to...

Which of the following macronutrients are least hydrophilic? Lipids Carbohydrates Nucleic Acids Proteins
1. Like phospholipids, lipopolysaccharides have a hydrophilic head and a hydrophobic tail. True or false 2. The outer membrane of Gram negative bacteria contains lipopolysaccharides T or F 3. Biofilms and pure culture are formed by only one type of microorganism T or F 4. Any given antibiotic will have the same minimum inhibitory concentration (MIC) against any test microorganism. T or F 5. Production of antibiotics by the microorganism is not affected by the culture conditions T or F...
1. Amino acids are considered to be either hydrophobic or hydrophilic as described by the relative polarity of their side chain. Consider a folded protein in an aqueous environment; where would the hydrophobic amino acids likely be found? -Tucked away in the middle of the folded protein -Randomly distributed throughout the protein -Exposed on the exterior surface of the folded protein 2. All proteins exhibit a primary, secondary, and tertiary structure, but not all proteins exhibit a quaternary structure. Describe...
What is phosphorus used for biologically other than ATP, nucleic acids, and phospholipids? I understand ATP is converted to ADP and energy for cellular functions is provided by this process, but can't remember where this happens or what role it plays with nucleic acids. I read that phosphorus containing compounds are important in photosynthesis as well, but the article didn't describe what the compounds were. The last question I have is what is phosphorus used for in plants? I know...
